<p>Definitely the issue of having to sell off all of my lenses and buy new ones for the GH4 is a huge drawback. I recall hearing there are adapters, not sure how well they work though, I need to do more research.<br>
As far as grading is concerned, my bread and butter are local TV commercials, so heavy color grades aren't really necessary. From what I've seen, the difference is pretty small between 8 bit and 10 bit w/o doing heavy grading.<br>
I think the Shogun has the ability to record into pro-res as well, which I hear is a better codec.<br>
Perhaps I'll take the wait and see approach here, and see if Canon steps up their game in 2015.</p>
<p>Thanks for your feedback.</p>
